Pumps ГРТ are intended for pumping over abrasive hydromixture at ore-dressing and processing enterprises, for example, for pumping out of the pulp received in the course of washing of rock (tails of ores black and nonferrous metals).
The horizontal pump is established with the electric motor on separate base frames. Connection of a shaft of the pump with electric motor shaft – rigid flanged. A material of a flowing part – special wear-resistant and corrosion-proof cast iron. The pump is delivered with a vertical or horizontal arrangement of a discharge nozzle.
Intervals of temperatures of a pumped over liquid from +1 to +70°С, density from 1100 to 1300 kg/m³. Admissible size firm particles in a pumping liquid - to 5 mm.
A symbol of the pump of type ГРТ:
2 – updating;
Гр – soil;
Т – two-case;
8000 – supply, m³/h;
71 – a head, m;
УХЛ4 – a climatic modification and a placing category.
An example: 2ГрТ8000/71-УХЛ4.
